Required Methods

fn query(&self, id: TypeId) -> Option<Box<dyn Any>>

fn process_read_buf( &self, io: &IoRef, stack: &Stack, idx: usize, nbytes: usize, ) -> Result<FilterReadStatus>

fn process_write_buf(&self, io: &IoRef, stack: &Stack, idx: usize) -> Result<()>

Process write buffer

fn shutdown(&self, io: &IoRef, stack: &Stack, idx: usize) -> Result<Poll<()>>

Gracefully shutdown filter

fn poll_read_ready(&self, cx: &mut Context<'_>) -> Poll<ReadStatus>

Check readiness for read operations

fn poll_write_ready(&self, cx: &mut Context<'_>) -> Poll<WriteStatus>

Check readiness for write operations
